update main.cpp for LilyGO T-Dongle S3 support and enhance detection methods

- Added configuration for LilyGO T-Dongle S3, including display and APA102 LED support. - Adjusted channel hopping sequence to descending order and reduced dwell time to 250 ms. - Updated detection methods to focus on IE fingerprinting, disabling other methods to reduce false positives. - Enhanced README to reflect changes in detection strategy and camera behavior observations. -Fixed Mario boot sounds. This commit improves the firmware's ability to detect Flock cameras by refining the detection logic and adapting to new hardware configurations. Corrected Mario sounds result in improved UX and satisfaction.
